Fin for Swimming, Diving and the Like

ABSTRACT

A fin includes a blade and a foot pocket mounted on a front end of the blade. The blade includes a rubber layer having two opposite sides, and two carbon fiber units mounted on the two opposite sides of the rubber layer respectively. The rubber layer is provided between the two carbon fiber units so as to enhance the elastic coefficient of the blade so that the blade has greater elasticity and flexibility. Thus, when the blade is worn by a user who is swimming or diving in the water, the blade can be flexed and deflected to respond to the moving direction of the water current so as to decrease the drag applied on the blade so that the blade is moved in the water easily, thereby greatly saving the user&#39;s energy.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a swimming tool and, more particularly,to a fin or flipper for swimming, diving and the like.

2. Description of the Related Art

A conventional fin, which is available for swimming, diving and thelike, comprises a blade and a foot pocket mounted on the front end ofthe blade. Thus, when a user wears the fin, the blade is moved in thewater with a larger contact area between the blade and the water currentto increase the moving speed of the fin in the water so as to aid theuser swimming or diving in the water. However, the blade is made of aharder material so that the user has to apply a larger force to swing ormove the blade, thereby wasting the user's energy, and thereby easilycausing an uncomfortable sensation or even danger to the user.

BRIEF SUMMARY OF THE INVENTION

In accordance with the present invention, there is provided a fin,comprising a blade and a foot pocket mounted on a front end of theblade. The blade includes a rubber layer having two opposite sides, andtwo carbon fiber units mounted on the two opposite sides of the rubberlayer respectively.

The primary objective of the present invention is to provide a fin withgreater elasticity.

According to the primary advantage of the present invention, the rubberlayer is provided between the two carbon fiber units so as to largelyenhance the elastic coefficient of the blade so that the blade hasgreater elasticity and flexibility.

According to another advantage of the present invention, when the bladeis worn by a user who is swimming or diving in the water, the blade canbe flexed and deflected efficiently to respond to the moving directionof the water current so as to decrease the drag applied on the blade bythe water current so that the blade produces a larger dynamic energy andis moved in the water easily and conveniently, thereby greatly savingthe user's energy, and thereby facilitating the user moving in thewater.

Further benefits and advantages of the present invention will becomeapparent after a careful reading of the detailed description withappropriate reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING(S)

FIG. 1 is a perspective view of a fin in accordance with the preferredembodiment of the present invention.

FIG. 2 is a side cross-sectional view of the fin as shown in FIG. 1.

FIG. 3 is an exploded cross-sectional view of the fin as shown in FIG.2.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1-3, a fin 10 in accordance with the preferredembodiment of the present invention comprises a blade 12 and a footpocket 11 mounted on a front end of the blade 12.

The blade 12 includes a rubber layer 14 having two opposite sides, andtwo carbon fiber units 13 mounted on the two opposite sides of therubber layer 14 respectively.

The rubber layer 14 is sandwiched between the two carbon fiber units 13.The rubber layer 14 includes a plurality of rubber pieces 141. Therubber pieces 141 of the rubber layer 14 are spaced each other. Therubber layer 14 further includes a plurality of spaces 142 definedbetween the rubber pieces 141.

Each of the two carbon fiber units 13 includes two carbon fiber layers130. Preferably, the two carbon fiber layers 130 of each of the twocarbon fiber units 13 laminate each other.

In practice, the rubber layer 14 is sandwiched between the two carbonfiber units 13 to enhance the elastic coefficient of the blade 12 sothat the blade 12 has greater elasticity and flexibility. Thus, when theblade 12 is worn by a user who is swimming or diving in the water, theblade 12 is flexed and deflected to respond to the moving direction ofthe water current so as to decrease the drag applied on the blade 12 bythe water current so that the blade 12 is moved in the water easily andconveniently, thereby saving the user's energy, and thereby facilitatingthe user moving in the water.

Accordingly, the rubber layer 14 is provided between the two carbonfiber units 13 so as to largely enhance the elastic coefficient of theblade 12 so that the blade 12 has greater elasticity and flexibility. Inaddition, when the blade 12 is worn by a user who is swimming or divingin the water, the blade 12 can be flexed and deflected efficiently torespond to the moving direction of the water current so as to decreasethe drag applied on the blade 12 by the water current so that the blade12 produces a larger dynamic energy and is moved in the water easily andconveniently, thereby greatly saving the user's energy, and therebyfacilitating the user moving in the water.

Although the invention has been explained in relation to its preferredembodiment(s) as mentioned above, it is to be understood that many otherpossible modifications and variations can be made without departing fromthe scope of the present invention. It is, therefore, contemplated thatthe appended claim or claims will cover such modifications andvariations that fall within the true scope of the invention.
